Hi guys I have a 95 chevy 4x4 350 I bought last fall. Good truck and all but I thought it was lacking power and sounded like it would miss every now and again. The first thing I did was change the plugs which seemed to have helped but still not what it should be. I went and bought plug wires today and went to change them. I checked the firing order on the manifold and looked at the distributer and noticed it wasnt in the order on the manifold which is18436572. My truck is running with a firing order of 12758346 slugish but not back firing or anything. What I would like to know is if it is out 180 degrees or more.

The correct firing order is 18436572, odd numbers 1,3,5,7 are on the drivers side, even numbers 2,4,6,8 are passenger side, from front to back. Clockwise around the cap looking down from aboveThe way you have it wired now doesn't match any of the other two ultra-performance firing order swap cams either that racers use, so that idea is out. I'm amazed it runs very well at all the way it is now
